Diamond Core Bits For Mining

Advantages

Bits for various applications

HangHua bit products for site investigation and core sampling in soft to medium hard shallow rock formations - both consolidated and fragmented, are the most cost effective tools available on the market today. The selection of bits is off course as always very imperative for successful operation.

A wide range of bits

The range include impregnated diamond bits for very hard formation, surface set diamond bits and poly-crystalline diamond composite bits (PDC) for softer conditions and tungsten carbide bits for soft formations and overburden.

Special bit tools for special applications

The portfolio is complete to fit all common core barrels, in metric and imperial standard design. A special range of bit tools is also available such as non coring bits, rod shoes, hole openers and special products to convert wire line drill rods to single tube core barrels.
